SU143700A1 - Apparatus for making hollow blocks from mineral, for example, slag melt - Google Patents

Description

Devices are known for making hollow blocks from mineral, for example, slag melt, by casting into molds with their shirts internally cooled with water. In this case, the forms can be made up into an endless conveyor belt, on which a stamping or pressing mechanism and an annealing chamber are placed.

The proposed apparatus for making hollow blocks from a mineral melt, such as slag, is intended for similar purposes. Compared with the known, the proposed device provides for the formation of a solid frame inside the melt due to its solidification around the hollow cores and thereby fixing the dimensions of the voids and the block itself, which is achieved by making the hollow core holders with internal cooling vertically lowered into the melt. The limitation of the sizes of the blocks manufactured on the conveyor when lowering the hollow cores into the melt is achieved by using an U-shaped chamber with holes on the conveyor. The holes in the lid serve to pass the void formers, the chamber during void formation together with the angular parts of the form passed through it forms a closed form.

FIG. 1 shows a diagram of the proposed device for the manufacture of hollow blocks from mineral, for example, slag melt, side view; in fig. 2 is an AA section, in FIG. 1 (water cooling of the conveyor link); in fig. 3 shows a longitudinal section of the proposed device; in fig. 4 shows a section along BB, in FIG. 3; in fig. 5 is a section along BB, in FIG. 3

The described device consists of moving ribbed water cooled or massive metal links /, which together

with water cooled boards, 2 form the molding cells TpaHcn bjJfe a.-:

The height of the ribs, which serve as partitions between the cells, exceeds the lateral milkings; Therefore, the capacity of the cells of the molding conveyor is determined by the dimensions in terms of the parts of the conveyor and the height of the side portions.

The on-board water cooled boards transfer to higher, also water-cooled walls 3 of the molding tunnel, which overlaps the top of the water-cooled cover 4. The cover has an outlet 5 and a large number of holes through which the water-cooled hollow cores 6 pass. The hollow cores are fixed to the massive catchment box 7.

A catch box 8 with a spring compensator 9 is attached to the water collection box. The shield moves along the guides 10 and is driven in a reciprocating motion by a special drive, which simultaneously moves the links of the conveyor.

By this, the movement of the void-forming agents is synchronized with the movement of the links. The link moves when the vortex formers are in their highest position. During the movement of the void-forming agents and keeping them in an extremely low position, the conveyor links do not move.

The water-cooled link of the molding conveyor is a ribbed hollow box. A water supply tube 12 is connected to the bottom of one of the ends of the box, which connects the box of the link of the conveyor to the water-receiving, open-top box 13 located above the link of the conveyor.

Inside the hollow box is an outlet tube / 4, one end of which is located in the upper part of the box of the conveyor link. The other end of the discharge tube comes out of the link box and is bent downwards.

The water receiving box has a length equal to the length of the link of the molding conveyor (along its longitudinal axis). It is rigidly attached to the link box (for simplicity, the fastener parts are not indicated) and moves together with the link.

The water receiving boxes attached to the links of the conveyor form a continuous series of vessels.

Above them passes the water supply pipe 15 with the processes downwards 16. The water receiving tray 11 is located under the lower ends of the discharge tubes.

During operation, the ribbed links /, moving between the side boards 2, form open-top cells.

The movement of the cells occurs intermittently. Having moved to the length of one link, the cells stop.

During one of the stops, the cells are filled with slag melt, which fills them to the upper edge of the board.

Excessive amount of melt either flows through the upper edges of the side boards, or, at its low mobility, is scooped toward the water-cooled scraper.

The cells are then moved to a molding tunnel formed by the water-cooled walls 3 and the water-cooled cap 4.

The entrance and exit of the tunnel is closed by the edges of the links.

Due to this, a closed molding chamber is formed, filled to a certain level with a slag melt.

In this position of the conveyor links, their movement is stopped. Following this, the drive mechanism through the stem begins to lower the holders 6.

Immersed in the melt, they displace a certain volume. The level of rdkilava is increased and it completely fills the forming chamber.

Air and gases, displaced from the molding chamber when the void-forming units are lowered, exit through the outlet 5.

When there is an excess of melt in the cells of the molding conveyor, when the entire volume of the molding chamber is filled with slag melt even before the hollow cores reach the lowest position, the lowering of the core formers stops without stopping the drive. This is due to the compression of the spring compensator 9.

In the downward position, the holders are for some time sufficient to create a solid framework around them.

After a certain exposure in the extremely low position, during which solid cages have formed in the block, the void-formers rise and extend beyond the limits of the molding chamber.

During the time of lowering, holding in the lower position and raising of the core-forming units, the next cell of the forming conveyor is filled with slag melt. During the movement of the molding conveyor, the core-formers are in an extremely high position. In this case, the cells with the molded blocks are moved out of the forming tunnel, and the cells with the slag melt enter into it. After this, the block forming cycle is repeated.

When the conveyor moves, the blocks left the forming tunnel go beyond the side boards and during the stop of the links are shifted from them by a special ejector perpendicular to the direction of movement of the links.

The blocks are then fed in the usual manner to tunnels or other furnaces where they are subjected to annealing.

Water cooling of all parts of the apparatus for making hollow core blocks from slag melt is carried out in the usual manner.

The water cooling of the moving links of the molding conveyor is due to the fact that water from the water supply pipe 15 through the processes 16 flows into the water intake boxes 13 and fills the hollow box // of the molding conveyor belt through the water supply pipes 12.

Heated by slag melt, water rises to the top of the hollow box and expelled by continuously flowing cold water flows through the outlet tube 14 into the water intake tray 17.
